PCE-GAN: A Generative Adversarial Network for Point Cloud Attribute Quality Enhancement based on Optimal Transport
Tian Guo, Hui Yuan, Qi Liu +3
Point cloud compression significantly reduces data volume but sacrifices reconstruction quality, highlighting the need for advanced quality enhancement techniques. Most existing ap…
Perceptual Quality Assessment of Trisoup-Lifting Encoded 3D Point Clouds
Juncheng Long, Honglei Su, Qi Liu +4
No-reference bitstream-layer point cloud quality assessment (PCQA) can be deployed without full decoding at any network node to achieve real-time quality monitoring. In this work,…
Perceptual Quality Assessment of Octree-RAHT Encoded 3D Point Clouds
Dongshuai Duan, Honglei Su, Qi Liu +4
No-reference bitstream-layer point cloud quality assessment (PCQA) can be deployed without full decoding at any network node to achieve real-time quality monitoring. In this work,…
No-Reference Point Cloud Quality Assessment via Weighted Patch Quality Prediction
Jun Cheng, Honglei Su, Jari Korhonen
With the rapid development of 3D vision applications based on point clouds, point cloud quality assessment(PCQA) is becoming an important research topic. However, the prior PCQA me…
Progressive Knowledge Transfer Based on Human Visual Perception Mechanism for Perceptual Quality Assessment of Point Clouds
Qi Liu, Yiyun Liu, Honglei Su +2
With the wide applications of colored point cloud in many fields, point cloud perceptual quality assessment plays a vital role in the visual communication systems owing to the exis…
Perceptual Quality Assessment of Colored 3D Point Clouds
Honglei Su, Qi Liu, Zhengfang Duanmu +2
The real-world applications of 3D point clouds have been growing rapidly in recent years, but not much effective work has been dedicated to perceptual quality assessment of colored…
Reduced Reference Perceptual Quality Model and Application to Rate Control for 3D Point Cloud Compression
Qi Liu, Hui Yuan, Raouf Hamzaoui +3
In rate-distortion optimization, the encoder settings are determined by maximizing a reconstruction quality measure subject to a constraint on the bit rate. One of the main challen…
Model-based Joint Bit Allocation between Geometry and Color for Video-based 3D Point Cloud Compression
Qi Liu, Hui Yuan, Junhui Hou +2
Rate distortion optimization plays a very important role in image/video coding. But for 3D point cloud, this problem has not been investigated. In this paper, the rate and distorti…
